Part 7: Frequently Asked Questions (FAQ)
Q1: Is the boardview the same for Rev 1.0 and Rev 2.0?
No. Always use the exact revision. Compal often moves components, changes resistor values, or re-routes power planes between revisions. Using Rev 1.0 data on a Rev 2.0 board can lead to incorrect probing. USB/Ports not working: Why this board fails Common

Common issues include:
Elias adjusted his magnifying loupe. He had already checked the basics. The DC jack was tight. The 19V rail was present at the first MOSFET, but it stopped there like a traveler at a locked gate. To find the culprit, he needed more than a multimeter; he needed the map. He double-clicked a file on his workstation. The
Common failure modes and likely culprits
- No power / no LED: blown DC jack, input fuse, damaged PMIC, or shorted capacitors on the input rail.
- Battery not charging: battery connector, fuel gauge IC, charging MOSFETs, or SMBus communication failure with the charger.
- No display but system runs: eDP/LVDS cable/connector faults, GPU power rail failure, or damaged eDP driver components.
- Intermittent boot or POST errors: failing RAM, corrupted BIOS (SPI flash), loose BGA solder joints under CPU or southbridge.
- Overheating/shutdowns: faulty thermal sensors, fan header issues, or degraded thermal paste and heatsink mounting.
